UNITED STATES \VILLIAM C. BRIDGES, OF KANSAS CITY, MISSOURI, ASSIGNOR .OF TIIREE- FOURTHS TO HENRY SLEEK AND EDGAR J. PENFIELD, OF SAME PLACE.

CYLINDER BREAKING-PLOW.

SPECIFICATION forming part of Letters Patent No. 426,908, dated April 29, 1890.

Application filed October 17, 1889- Serial No. 827,274. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM C. BRIDGES, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Cylinder Breaking-Flows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in cylinder breaking-plows; and it consists in the novel construction and arrangement of its different parts, hereinafter set forth and described.

In the drawings, which illustrate the manner of carrying out my invention, Figure 1 is a side elevation of my device. Fig. 2 is a top plan view of the same. Fig. 3 is a detail in perspective of the hoop F, to which the revolving knives O are securely bolted. Fig. 4 is a rear view. Fig. 5 is a perspective detail View showing the swinging truck secured to the axle and tongue by suitable ratchets O and eccentric-shaft K together with the swinging rods L. Fig. 6 is a detail in perspective of the stationary cog-wheel G, which is secured on a square shaft G, which in turn op crates through the truck-frame I in such a manner that when thrown in gear by lever H the truck and cylinder plow are lifted out of the ground by gear-wheel D. Fig. 7 is a detail in perspective of the cylinder plow, showing the knives O in position. Fig. 8 is a detail in perspective of the cylinder-head B, showing lugs B,which form proper bearings for knives C. Fig. 9 isasectional View taken through center of Fig. 8. Fig. 10 is a detail view of the bolt to and nut a by which knives O are secured to lugs B and hoops F. Fig. 11 is a detail in perspective of one of the knives 0.

Referring to the drawings by letter, A represents my invention; B, the cylinder-head, the same being provided with lugs B, as illustrated in Fig. 8. Said lugs B are cast together with said cylinder-head, so that they are stationary and form rigid bearings for the knives O. Said knives O are provided with perforations a, by which they are rigidly secured to the revolving cylinder-heads B B and hoops F F.

E is a small cog-Wheel which gears with the larger cog-wheel D in such a manner that it can be thrown in or out of gear at will by operating lever M, which is rigidly secured to eccentric-shaft K.

E is a shaft passing through the center of the cylinder-head, the ends forming proper bearings on truck-frame I, also forming the axis of said cog-wheel E.

F are the hoops heretofore referred to and 6c are made in the manner illustrated in Fig. 3, and are for the purpose of holding the knives rigid while in operation.

G is a stationary cog-wheel keyed or otherwise rigidly secured to square shaft G ,which operates in truck-frame I in such a manner as to be thrown in and out of gear with cogwheel D for raising said cylinder plow and truck-frame when not in use.

H is the lever-arm by which said stationary 7o cog is operated, the same being secured to axle e by bolt h.

I I are the sides of truck-frames heretofore referred to; J, the front piece of said truck-frame.

K is the eccentric rod by which truckframe I is thrown forward or backward in such a manner that the cog-wheels E and D are thrown out of gear.

L are the swinging arms, which are secured around eccentric is in the manner illustrated in Fig. 5. Said arms L are secured in a proper manner to truck-frame I by suitable nuts.

M is a lever-arm (placed at opposite end of axle from the lever-arm H) which is rigidly secured to eccentric-shaft K in such a manner that the cylinder plow may be thrown in and out of gear by the driver, who sits on a suitable seat 2'.

N is across-bar secured to the top of tongue b in a suitable manner. To this are secured ratchets O, which hold the truck-frame in the desired position.

a are the bolts, heretofore referred to, by which the knives O are firmly secured to cyl- 5 inder-heads B and hoops F.

b is a tongue made of suitable material and properly braced, as illustrated in Fig. 5, by

braces c c.

cog-wheel D to the carriage-wheels g g.

E is the axle heretofore referred to.

f are the perforations in hoops F, through which pass bolts to.

71 is the seat, heretofore referred, to secured on a suitable bearingspringj.

713 is the eccentric to rod K, which lifts truck-frame I and gear-Wheel E out of position when so desired.

7c are suit-able staples by which eccentricshaft K is properly secured to axle e.

Z are the edges 01' the cylinder-head B, showing the manner in which they are made.

at is the doubletree, which is secured on cross-bar N by a suitable bolt. n are singletrees secured in a suitable manner to said doubletree n.

It will be seen that I have provided a dru 111 m, which passes over the upper portion of the cylinder plow and is properly secured to the truck-frame to prevent the soil from being thrown over the machinery.

My cylinder plow is designed to enter the ground to the depth of about six inches, as illustrated in Figs. 1 and i, being operated by gear-wheels D and E in the manner illustrated and described.

Having thus fully described my invention,

nation of the fran1e,a cylinder carried thereby, the heads of which are provided with a series of i11wardly-extending, projections, and knives secured to the said projections, and mechanism for elevating or depressing the cylinder.

In testimony whereof I affix my signature in presence of two witnesses.
